NATHANIEL DAVIS, OF MONTPELIER, VERMONT, ASSIGNOR TO GEORGE Il. DAVIS,.OF NORTH ANDOVER, MASSACHUSETTS.

WATER-COOLER.

SPECIFICATION forming part of Letters Patent No. 398,770, dated February 26, 1889. Application filed August 13, 1888. Serial No. 282,566. (No model.)

To all wtom i may concern.-

Be it known that I, NATHANIEL Davis, of Montpelier, county of Washington, State of Vermont, have invented an Improvement in vWater-Coolers, of which the following description, in connection with the accompanying drawings, is a specificati on, like letters and iigures on the drawings representing like parts.

This invention has for its object the production of a water-cooler which is effect-ive with but little ice.

In accordance with my invention I provide a box Within which I place a stone jar having above its cover an ice-chamber, the said jar having a faucet by which to draw from it the cold water. I have also shown the jar as being capable of being filled Without removing the cover. To facilitate the cooling actionvof the descending cold air and the Water from the melted ice, I have provided the jar at its exterior With spiral grooves or troughs in which the air and Water are caught and made to rest, so as to gradually reach the bottom of the jar.

My invention in a cooler consists in the combination, With a surrounding jacket or case and a covered jar, of an ice-receptacle located immediately above i`n contact with the cover ort-op of the jar, and a faucet or outlet leading from the jar out through the jacket or case.

Other features of my invention ivill be herein described, and pointed out in the claims at the end of this specification.

Figure l is a vertical section of a water or liquid cooler embodying my invention, and

Fig. 2 a vienT of the jar removed.

The jacket or casing A is herein shown as having double Walls, as a a', suiiiciently removed from each end to leave air-chambers, which are subdivided b vpartitions l), preferably of paper or some other thin cheap material, treated With paraiiine or other equivalent I substance to render the partition substantially Water-repellent and air-proof. The lid B of the jacket or casing, hinged at 2, is also shown as made in like manner to leave airchambers therein. The bottom of the jacket is provided with a Water-outlet, as b', which is closed by a screw-plug, b2. l

I/Vithin the jacket I have placed avertical Wall, c, which terminates short of the inner bottom of the jacket, so as to leave an airpassage, 3, the interior of the jacket between the division-Wall c and one side of the jacket having a horizontal shelf, as c', which, as shown, serves to support the ice-chamber d, which will preferably be of metal iianged over at its top to form a lip, Li, and contracted at its lower end to come close to the cover e of the jar f of stone or other usual material, the cover forming the bottom thereof.

The jar f is provided at its outer side with ribs or channels 6, preferably extended about the jar, as best shown in Fig. 2, so that the Water from the melting ice in the chamber d, as it passes from the cover, will follow down over the body of the jar, slowly running around and around the jar, and, further, the cold air in the chamber or space between the jar and the partition c and the inner Wall, d, as it descends is made to settle more slowly by reason of the channels 6.

Any air at the bottom of the jar which is sufficiently light or Warm to rise has opportunity to do so in the space g, and to enter lthe ice-chamber.

The cold Water in the jar f may be drawn out through the outlet-pipe or faucet h.

The Water to be cooled may be introduced into the jar by an inlet-pipe, as in., extended through the ice-chamber and into the cover e.

The apparatus herein shown forms a most excellent Water or liquid cooler, which is very eflicient in operation, and may be run with but a small amount of ice.

Although I prefer to make the jacket or I casing as shown, yet it may be made as are the Walls of any usual refrigerator-box Without departing from my invention.

Preferably the jar Will be made as shown, yet the channels 6 might be omitted, and such a jar combined with the cover and ice-chamber and jacket would produce a very good water-cooler.

I claiml. The jacket or casing and the jar f and its outlet h, extended through the jacket or casing, combined with the cover e, for the jar, and the iceechamber d, located immediately above the said cover, the cover forming the bottom of the icechaniber, and an inlet-pipe IOO for the said jar extended through the icethrough the ice-chamber into the jar,substan chamber, substantially as shown and detially as described. scribed. In testimonywhereof I have signed my 2.

It is hereby certified that Letters Patent No. 398,770, granted February 26, 1889, upon the application of Nathaniel Davis, of Montpelier, Vermont, for an improvement in Water Coolers, was erroneously issued to George L. Davis as sole owner ofthe t patent; that said Letters Patent should have been issued to said Nathaniel Davis and George L. Davis, jointly, said George L. Devis being assignee of one-half interest only as shown by the record of assignments in this Office 5 and that the proper correction has been made in the tiles and records of the ease in the Patent Oie'e, and should be reed in the Letters Patent that the same may conform thereto.
